DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Hereinafter, exemplary embodiments will be described in greater detail with reference to the accompanying drawings. Various changes, modifications, and equivalents of the systems, apparatuses and/or methods described herein will suggest themselves to those of ordinary skill in the art. Descriptions of well-known functions and structures are omitted to enhance clarity and conciseness. Elements, features, and structures are denoted by the same reference numerals throughout the drawings and the detailed description. The size and proportions of some elements may be exaggerated in the drawings for clarity and convenience. The term “unit” as used herein may include a hardware component and/or a software component that is executed by a hardware processor.

FIG. 1 is a block diagram illustrating a detailed configuration of a display apparatus 100 according to an exemplary embodiment. The display apparatus may be embodied as a TV. The display apparatus 100 comprises a broadcast receiving unit 110, an audio/video (A/V) processing unit 120, an audio output unit 130, a display unit 140, a storage unit 150, a communication unit 160, a remote control receiving unit 170, and a controller 180.

The broadcast receiving unit 110 receives a broadcast via a wired or wireless connection from a broadcasting station or satellite, and demodulates the received broadcast. The broadcast receiving unit 110 may receive broadcast information.

The broadcast receiving unit 110 separates the received signals into an image signal and an audio signal and transmits the image signal to the A/V processing unit 120.

The A/V processing unit 120 performs signal processing, such as video decoding, video scaling, or audio decoding, on the image signal and the audio signal input from the A/V processing unit 120. The A/V processing unit 120 outputs the image signal to the display unit 140, and outputs the audio signal to the audio output unit 130.

The audio output unit 130 outputs audio output received from the A/V processing unit 120 through a speaker, or outputs the audio to external devices (for example, an external speaker) connected through external output terminals.

The display unit 140 displays an image output from the A/V processing unit 130 on a screen. That is, the display unit 140 displays a broadcast image corresponding to a broadcast signal.

Moreover, the display unit 140 may display a search window on a partial area of the screen. The search window corresponds to a window provided to perform a simple Internet information search. That is, the search window is a window that is displayed by an application for performing an Internet search based on keyword input. The search window functions to search various Internet sites and information that can be searched via the Internet and displays search results.

The search window includes a search keyword input region for inputting a search keyword by a user and a search result display region for displaying a search result. The search window has three modes: a first mode; a second mode; and a third mode.

The first mode is a mode in which the search window is minimized. The search window in the first mode displays search results one by one on the search result display region. Since the first mode is a mode in which the search window is minimized, the user can concentrate their attention on the display.

The second mode is a mode in which the search window size is larger than that in the first mode. The search window in the second mode displays two or more search result entries, because the search result display region becomes larger. The user can concentrate their attention more on search since the size of the search window in the second mode is increased.

The third mode is a mode in which the search window is displayed in full screen. Moreover, the search window in the third mode may display various information, as well as the search keyword input region and the search result display region. The search window in the third mode may be converted into a web browser.

In addition, the display unit 140 may display an image display window. The image display window is a window for displaying a broadcast image, e.g., a TV broadcast image, or input image being currently displayed in a partial area of the screen.

The storage unit 150 stores programs for operating the display apparatus 100. Moreover, the storage unit 150 may store recorded image files. The storage unit 150 may be implemented as a hard disk, a non-volatile memory, etc. but is not limited thereto, and any equivalent structure for performing the function of storing as would be understood by those skilled in the art may be used without departing from the scope of the invention.

The communication unit 160 connects the display apparatus 100 to a communication network, such as the Internet, to enable communication. Specifically, the communication unit 160 is connected to a search engine server providing an Internet search service over the communication network. Then, the communication unit 160 transmits an input keyword to the search engine server, and receives search results for the keyword.

The remote control receiving unit 170 receives a command from a remote control 175 and transmits the command to the controller 180. Specifically, the remote control receiving unit 170 receives a user's operation input from the remote control to change the size of the search window.

The controller 180 determines the user's command based on the content of the user's manipulation transmitted from the remote control 175, and controls the entire operation of the display apparatus 100 according to the user's command.

More specifically, the controller 180 controls the search window for performing an Internet search to be displayed on a partial area of the screen where an image is displayed. Then, upon receiving a specific manipulation input by the user, the controller 180 converts the search window into the image display window. At this point, the controller 180 may control the image display window to be displayed in the same size as the search window when the search window is converted into the image display window.

The specific manipulation is a manipulation that generates an event for causing the controller 180 to convert the search window into the image display window. The specific manipulation may be a manipulation that makes the search window displayed on the full screen. In this case, upon receiving a specific manipulation input, the controller 180 converts the search window on the display into the image display window. Then, the controller 180 refreshes the display of the search window on the full screen.

Moreover, the specific manipulation may refer to a manipulation for changing the size of the search window to a size greater than a preset size. In this case, upon receiving a specific manipulation input, the controller 180 converts the displayed search window into the image display window. Then, the controller 180 controls the search window to be displayed in the changed size.

The specific manipulation may refer to a manipulation that selects an icon for converting the search window to the image display window. In this case, upon receiving an input of a selection manipulation on the icon, the controller 180 converts the search window on display into the image display window.

Furthermore, the specific manipulation may refer to a touch and drag operation on the search window. Here, the touch and drag operation is touching the screen of the area where the search window is displayed, moving it in a particular direction, and dropping it. Upon receiving an input of a touch and drag operation on the search window, the controller 180 converts the search window into the image display window.

The controller 180 can convert the search window into the image display window by various manipulations. Accordingly, the user can view an image as well while doing a search on the display apparatus.

Further, the controller 180 controls such that the search window is displayed on a partial area of the screen where an image is displayed, and such that, upon receiving a search command input through the search window, as many search results as a preset number of result displays are displayed on the search window. Here, the preset number of result displays is the number of search result entries displayed at one time on the search result display region. That is, the controller 180 sets the number of search result displays to 1 when displaying the search window in the first mode.

Upon receiving a first manipulation input by the user, the controller 180 increases the number of result displays displayed on the search window. That is, the controller 180 converts the search window from the first mode to the second mode. Then, the controller 180 converts the number of search result displays from 1 to N (where N is a natural number of 2 or more).

To this end, the controller 180 increases the size of the search result display region of the search window and increases the entire size of the search window. At this point, the controller 180 determines the relative size of the search window, taking the entire size of the screen into consideration. For example, the controller 180 may determine the size of the search window of the second mode to be ⅓ the full screen size.

As used herein, the first manipulation corresponds to a manipulation in which a command is entered more a particular number of times to turn search results displayed in the search result display region in units of the number of search displays. That is, the first manipulation is a manipulation in which a command for turning the pages of search results is entered more than a particular number of times. For example but not by way of limitation, when the user has entered a command for turning over the pages of search results three times, the controller 180 may convert the search window from the first mode to the second mode on the point of time when the page turn command has been entered three times.

Frequent inputs of the page turn command by the user represent the user's intention to focus on finding desired search results. Therefore, when the user has entered the command for turning over the pages of search results more than a particular number of times, the controller 180 automatically enlarges the size of the search window to increase the number of search results displayed at one time.

The controller 180 may convert the search window to the third mode for displaying the search window in full screen upon receiving a second manipulation input by the user. Here, the second manipulation corresponds to a manipulation for changing the size of the search window to more than half of the full screen size. As such, enlargement of the size of the search window to more than half of the full screen size represents the user's intention to focus on the search. Therefore, the controller 180 displays the search window in the third mode upon receiving the second manipulation input.

At this point, when the search window has been converted to the third mode, the controller 180 may control such that the image display window, which has been displaying an image, may be displayed on a partial area of the screen. This is for the user to view the TV broadcast screen even when the search window is displayed in full screen.

Additionally, the controller 180 may bookmark at least one of the entries included in the search results according to the user's selection. Further, upon receiving a third manipulation input by the user, the controller 180 may control such that as many bookmarked entries as a preset number of result displays, among the search results, on the search window, may be displayed. Here, the third manipulation is a manipulation for entering a command to display only the bookmarked search result entries.

As such, the user can check only the bookmarked entries again or check them individually because the user can bookmark desired entries among the search result entries.

As a consequence, the controller 180 can change the size of the search window variously according to a situation. Accordingly, the user can check search results more conveniently by using the search window.

Hereinafter, a method for providing a search service will be described in detail with reference to FIGS. 2A-2B, 3 and 4. FIGS. 2A and 2B are flowcharts provided to describe a method for providing a search service according to an exemplary embodiment.

FIG. 2A is a flowchart for describing a process of converting the search window into the image display window.

The display apparatus 100 displays a broadcast image (S201). In this state, when a search window execute command is entered by a user, the display apparatus 100 displays the search window in the first mode on a partial area of the screen (S202).

In this state, the display apparatus 100 checks whether a specific manipulation is entered (S203). Here, the specific manipulation is a manipulation that generates an event for causing the display apparatus 100 to convert the search window to the image display window. If a specific manipulation is entered (S203-Y), the display apparatus 100 converts the search window into the image display window (S204). If a specific manipulation is not entered, the checking at S203 is repeated.

The specific manipulation may refer to a manipulation for displaying the search window in full screen. In this case, upon receiving the specific manipulation, the display apparatus 100 converts the search window on display into the image display window. In this case, the display apparatus 100 refreshes the full-screen display of the search window.

The specific manipulation may refer to a manipulation for changing the size of the search window to a size greater than a preset size. In this case, the display apparatus 100 displays the search window in the changed size.

The specific manipulation may refer to a manipulation for selecting an icon for converting the search window to the image display window. In this case, upon receiving an input of a selection manipulation on the icon, the display apparatus 100 converts the search window on display into the image display window.

The specific manipulation may refer to a touch and drag operation on the search window. Here, the touch and drag operation is touching the screen of the area where the search window is displayed, moving it to a particular direction, and dropping it. In this case, upon receiving an input of a touch and drag operation on the search window, the display apparatus 100 converts the search window to the image display window.

By this process, the display apparatus 100 can convert the search window into the image display window by various manipulations. Accordingly, the user can view an image as well while doing a search on the display apparatus.

Hereinafter, a process of changing the size of the search window will be described with reference to FIG. 2B. First, the display apparatus 100 displays a broadcast image (S210). In this state, when a search window execute command is entered by a user, the display apparatus 100 displays the search window in the first mode on a partial area of the screen (S220).

Specifically, the display apparatus 100 performs control such that the search window is displayed on a partial area of the screen where an image is displayed, and such that, upon receiving a search command input through the search window, search results up to a preset number of result displays are displayed on the search window. The preset number of result displays is the number of search result entries displayed at one time on the search result display region. That is, the display apparatus 100 sets the number of search result displays to 1 when displaying the search window in the first mode.

When a search keyword is entered into the search window by the user (S230-Y), the display apparatus 100 displays search results one by one on the search result display region (S240). If a search keyword is not entered, S230 is repeated. Upon the initial execution of the search window, the search results are displayed one by one on the search result display region because the search window is set to the first mode.

Afterwards, the display apparatus 100 determines whether a next page display command on the search results is entered (S250). If the next page display command is entered (S250-Y), the display apparatus 100 determines whether the number of next page display command inputs exceeds a preset number (S260). If the next page display command is not entered, S250 is repeated. If the number of next page display command inputs does not exceed the preset number (S260-N), the display apparatus 100 displays the next page of the search result entries (S240).

If the number of next page display command inputs exceeds the preset number (S260-Y), the display apparatus 100 enlarges the size of the search window (S270). Therefore, the display apparatus 100 converts the number of search displays displayed on the search window from 1 to N (where N is a natural number of 2 or more). That is, the display apparatus 100 converts the search window from the first mode to the second mode.

At this point, the display apparatus 100 determines the size of the search window, taking the entire size of the screen into consideration. For example, the display apparatus 100 may determine the size of the search window of the second mode to be ⅓ the full screen size.

As used herein, the first manipulation corresponds to a manipulation in which a command is entered more a particular number of times to turn over search results displayed in the search result display region in units of the number of search displays. That is, the first manipulation is a manipulation in which a command for turning over the pages of search results is entered more than a particular number of times. For example, when the user has entered a command for turning over the pages of search results three times, the display apparatus 100 may convert the search window from the first mode to the second mode on the point of time when the page turn command has been entered three times.

Frequent inputs of the page turn command by the user represent the user's intention to focus on finding desired search results. Therefore, when the user has entered the command for turning over the pages of search results more than a particular number of times, the controller 180 automatically enlarges the size of the search window to increase the number of search results displayed at one time.

Accordingly, the display apparatus 100 converts the search window into the second mode, and displays N search result entries per display on the search result display region (S280).

Frequent inputs of the page turn command by the user represent the user's intention to focus on finding desired search results. Therefore, through this process, when the user has entered the command for turning over the pages of search results more than a particular number of times, the display apparatus 100 automatically enlarges the size of the search window to increase the number of search results displayed at one time.

The display apparatus 100 may bookmark at least one of the entries included in the search results according to the user's selection. Further, upon receiving a third manipulation input by the user, the controller 180 may perform control such that as many bookmarked entries as a preset number of result displays, among the search results on the search window, may be displayed. Here, the third manipulation is a manipulation for entering a command to display only the bookmarked search result entries.

As such, the user can check only the bookmarked entries again, or check them individually, because the user can bookmark desired entries among the search result entries.

As a consequence, the controller 180 can change the size of the search window variously according to a situation. Accordingly, the user can check search results conveniently by using the search window.

Hereinafter, a process for converting the search window into the third mode will be described with reference to FIG. 3. FIG. 3 is a flowchart provided to describe the full-screen display of the search window according to an exemplary embodiment.

With the search window being on display, the display apparatus 100 determines whether a search window size change command is entered (S310). If the search window change command is entered (S310-Y), it is determined whether the changed size of the search window is more than half the screen size (S320). If the search window change command is not entered, then S310 is repeated.

If the changed size of the search window is no more than half the screen size (S320-N), the display apparatus 100 displays the search window in the changed size (S340). If the changed size of the search window is more than half the screen size (S320-Y), the display apparatus 100 displays the search window in full screen (S330). That is, the display apparatus 100 executes the search window in the third mode.

When the search window has been converted to the third mode and displayed in full screen, the display apparatus 100 may control such that the image display window, which has been displaying an image, may be displayed on a partial area of the screen. This is for the user to view the broadcast screen even when the search window is displayed in full screen.

The display apparatus 100 may display a message asking the user whether to display the search window in full screen before displaying the search window in full screen. If the user enters a select command for displaying in full screen, the display apparatus 100 may be implemented to convert the search window into the full screen.

In this way, if the user enlarges the size of the search window, the display apparatus 100 regards this as an intention to focus on the search and displays the search window in full screen.

Hereinafter, a process of displaying an image on display on a partial area of the screen will be described with reference to FIG. 4. FIG. 4 is a flowchart provided to describe a process of displaying an image display on a partial area of the screen when the search window is displayed on the screen according to an exemplary embodiment.

First, the display apparatus 100 displays a broadcast image (S410). Then, when a search window display command is entered from the user, the search window is displayed on a partial area of the screen (S420).

When a command for conversion into the full screen is entered from the user (S430-Y), the display apparatus 100 displays the search window in full screen (S440). If no command for conversion is entered, S430 is repeated. In this state, the display apparatus 100 displays the image display window, which has been displaying the broadcast image, on a partial area of the screen (S450). That is, the display apparatus 100 displays the search window in full screen, and converts the existing search window on display into the image display window. Thus, the display apparatus 100 displays the broadcast image in a picture-in-picture (PIP) format on a separate image display window.

Accordingly, the display apparatus 100 can change the size of the search window variously according to a situation. Accordingly, the user can check search results conveniently by using the search window.

FIG. 5 is a view illustrating a structure of a search window according to an exemplary embodiment.

The search window 500 comprises a search keyword input region 510 and a search result display region 520.

The search keyword input region 510 is a region into which a search keyword is entered by the user. The search result display region 520 is a region in which information searched by the search keyword is displayed.

The search window 500 shown in FIG. 5 is a search window corresponding to the first mode. Accordingly, it can be observed that only one search result is displayed in the search result display region 520 of the search window 500.

The search window 500 may display a keyword recommendation list 530. The keyword recommendation list 530 is a list of keywords which are extracted by taking into account the search history of the user and displayed y the display apparatus 100.

FIGS. 6A to 6D are views illustrating the process of changes of the search window for each mode according to an exemplary embodiment. FIG. 6A depicts the search window 610 being displayed in the first mode when a broadcast image is displayed on the screen of the display apparatus 100.

As illustrated in FIG. 6A, the display apparatus 100 displays the search window 610 of the first mode on a partial area of the right lower part of the screen. Only one search result is displayed on the search window 610.

In this state, when the user enters the left button or right button of the remote control, the display apparatus 100 changes the search result displayed on the search window to the previous result entry or the next result entry.

If a manipulation for turning to the next result entry is entered more than a particular number of times, the display apparatus 100 converts the search window into the search window 620 of the second mode as shown in FIG. 6B.

As shown in FIG. 6B, three search result entries are displayed on the search window 620 of the second mode. In this case, the number of search result displays is set to a3.

When a full screen display command is entered by the user, the display apparatus 100 displays the search window 630 of the third mode as shown in FIG. 6C. The search window 630 of the third mode is a search window displayed on the full screen.

In this state, if the user selects “Search Result 2” from among the search results, the display apparatus 100 displays a web browser screen 640 connected to the site corresponding to “Search Result 2” as shown in FIG. 6D.

The display apparatus 100 can thus adjust the size of the search window to various sizes according to a situation.

Moreover, the remote control may include a pointing function. That is, the remote control may include a user interface function for pointing a specific point of the screen of the display apparatus 100. To implement this function, the remote control may comprise a Gyro sensor and an acceleration sensor. In this case, the touch and drag of a touch operation, corresponds to the point and drag of a pointing operation. Therefore, when a point and drag operation is entered through the remote control, the display apparatus 100 recognizes this as a command for conversion between the image display window 1600 and the search window 1610.

While an application screen displayed for search has been referred to as a search window in this exemplary embodiment, the use of this term is only for purposes of convenience, and is not limited to the form of a window.

Although the exemplary embodiments have been described supposing that the display apparatus is a TV, any device may be applied as the display apparatus if only it is capable of performing an Internet search function. For example, the exemplary embodiment may also be applied to a case in which the display apparatus is a mobile communication device such as a handheld phone, a personal music player (PMP), an MP3 player, etc.

The above-described embodiments can also be embodied as computer readable codes which are stored on a computer readable recording medium (for example, non-transitory, or transitory) and executed by a computer or processor. The computer readable recording medium is any data storage device that can store data which can be thereafter read by a computer system.

Examples of the computer readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and carrier waves such as data transmission through the Internet. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
